Great moderate hike. I am 45 and fit but I def felt it the next day. I live in Tarzana right below the trail head at Marvin Braude Gateway. I left the house on sat 7:30am and it was buzzing with bikes and hikers on the valley side. The middle stretch I had mostly to myself with the occasional random human being every 30 mins. It was very busy on the Temescal Trail portion. Took me 3.5 hours to reach the beach at Will Rogers. Beautiful trails. Mostly fire roads on the valley side that change to goat paths along the ridges and canyons of Topanga / Temescal. The worst part was walking Temescal Canyon Road to get to the beach.
